POWDER-BLOWER.

SPECIFICATION forming part of Letters Patent No. 465,484, dated December 22, 1891. Application filed October 1,1891. Serial No. 407,406. (No model.)

To all whom it may concern:

Be it known that I, ANTHONY EUGENE MA- GORIS, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Powder-Blowers and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to that class of powder-blowers in which a rubber bellows is used; and my object is to produce a more durable and effective device than those hitherto in vogue; and to this end my invention consists in the peculiar features and combinations of parts more fully described hereinafter, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a transverse section of my complete invention, and Fig. 2 an exterior perspective view.

The bellows a consists of a hollow ball or bulb of rubber, such as ordinarily usedin powder-blowers. A circular recess is made in one side of the ball and receives a tubular metallic socket b, which projects inwardly and is provided with a lateral circular shield c, corresponding in form to the circumference of the ball. The outer surface of the ball is cemented or otherwise hermetically sealed to the under side of the shield. This socket 1) forms the only outlet-orifice and receives a nozzle d, having a tapering end provided with a discharge-orifice e. The exterior of the opposite end of the nozzle is smooth and fits snugly within the socket b. An inverted diskshaped plate fis fastened to the outside of the socket b, and a helical spring 9 is attached to the plate. The general outline of the spring is that of an inverted cone truncated at the end farthest from the nozzle. Over this spring and its supporting-plate is stretched a porous powder receptacle or sack, its edges at the top being interposed and fastened between the shield c and top of plate f, which, together with the rubber bulb, form an'air-tight joint. This porous sack is, by preference, made of cloth through which the air can pass, although the sack can be made of any other porous material non-soluble, impervious to the effects rubber that the cloth or other impervious receptacle for the powder is employed.

Then the sack is filled with powder and the bulb allowed to expand, air will be sucked in through the nozzle and porous sack into the air-space around the latter, and when the bulb is compressed the air within is forced out through thepores of the sack and carries 7o the powder with it. In the outward passage of the air the sack is prevented from collapsing and stopping the exit by means of thespring g; but the spring and sack can be compressed togcther with the rubber bulb when the latter is sufficiently indented or compressed at the bottom. The retractile force of the spring makes the latter quickly expand with the bulb as soon as pressure is released. It will thus be seen that the powder is actively stirred and prevented from caking or clogging, that there is no valve to get out of order, that the rubber does not become inj ured and lasts infinitely longer, and that the device is cheap, strong, effective, and durable. 8 5

It is evident that my invention could be varied in many ways that would naturally sug gest themselves to a skilled mechanic. Therefore I do not limit myself to the exact construction shown, but consider myself entitledv go to all such variations as come within the spirit and scope of my invention.

Having thus described myinven tion, what I claim as new, and desire to secure by Letters Patent, is-

In a powder-blower, a rubber bulb or bellows provided with an outlet-orifice, in combination with a porous sack or powder-receptacle located within the bulb and having its mouth placed over said orifice, said sack beoo ing composed of non-soluble material,substantially as and for the purpose set forth.
